Hi, I am new to R and to this Forum, so I am not sure if this is the correct space to "Reply" or not. However, I keep getting the same error message that Jay got above even after I deleted both R and bear from my computer (Windows) and the Re-installed R 4.0.0 and bear successfully in that order. I did that twice and still got the same error message.
I am glad to see that I am not alone on this and that you are working on a solution. Would the new version 2.8.8 also work for in Windows?
Thanks - Andrew S
